"ITMS-90034: Missing or invalid signature" when uploading new version to the apple store

I tried to upload a new version (trstflight build) for IOS to apple. The app is already online and this worked in the past. Today I get the error message"ITMS-90034: Missing or invalid signature" - The bundle … at bundle path ‘Payload/AdaloApp.app’ is not signed using am Apple submission certificate.
Does anybody have an idea?

Same here. But I did rebuild again, then it worked! Perhaps it was wrong way to built android and ios simultaneously.

I got this problem today. It was good until last 2 versions. I did not change anything in app.
